Filed: 1948-09-13
Abstract: 645,734. Bearings. TRIST, A. R. Sept. 13, 1948, No. 23985. [Class 12 (i)] In a bearing for a rotating shaft a wherein bushes or sleeves b, b<SP>1</SP>, b<SP>2</SP> are interposed between the surface of the shaft and its stationary bearing surface c, the speed of each bush is controlled by means mounted on each bush and responsive to the centrifugal force generated by the rotation of the bush. The control means may comprise thin flat circularly curved springs e, h, each of which is attached at one of its ends to a bush, and at the other to a shoe d, g. Each shoe d constitutes an "urging"  shoe and may engage either the shaft a or the external surface of the next smaller bush or sleeve, and each shoe g constitutes a "checking" shoe which may engage either the stationary bearing surface c or the internal surface of the next enclosing bush or sleeve. The speed of each bush or sleeve is controlled so that the relative velocity of all the surfaces in sliding contact is substantially the same. Two shoes d and two shoes g are attached to each bush or sleeve.

Title: Method of treating tobacco and apparatus therefor
IPC: A24B3/18
Filed: 1951-10-15
Abstract: Tobacco, either in a closed chamber or fed continuously by belt, worm or other conveying means through a tube, is treated for a few minutes by a high-frequency electric field in such a way that the tobacco attains a temperature of about 100 DEG C or somewhat higher, and resulting gaseous, vaporous or volatile constituents, which may be reaction products of nitrogenous and other undesirable constituents of the original leaf, are permitted, as by tobacco aeration and cooling, to escape at the end of the treatment, e.g. together with steam produced from moisture in the tobacco.  Pre-treatment with steam and/or sauce substances and/or chemicals may be effected.  The initial relative humidity of the tobacco is suitably between 18 per cent and 25 per cent.  The chamber or tube is of non-conducting material such as porcelain, earthenware or glass.  More than one high-frequency generator may be used in the continuous-feed method, but the chamber is situated between the electrodes of a single generator.

Patent GB-886523-A (GB)
Title: Improvements relating to the production of carbon black
IPC: C09C1/50
Filed: 1959-07-14
Abstract: Black of low modulus is produced by decomposition of a hydrocarbon in the presence of one or more alkali metals added as such or as a compound.  Alkali metals specified are lithium, sodium, potassium, rubidium, cesium, and francium.  Compounds specified are hydroxides, chlorides, sulphates, carbonates, salts with organic acids, and metal alkyls.  1-100,000 parts of alkali metal per million parts of black produced may be added.  The alkali metal may be added as a solid, liquid, or vapour.  It may be dissolved or suspended in a liquid carrier, e.g. water or liquid hydrocarbon make material, or suspended in a gas or vapour, e.g. combustion air or fuel gas.  The black may be produced by injecting a liquid make hydrocarbon, e.g. a furfural extract or a residual tar from a residual cycle stock, axially into a cylindrical furnace and decomposing the hydrocarbon in a surrounding spiral stream of burning natural gas, or by thermally decomposing natural gas diluted with hydrogen in a chamber previously heated by combustion.  Examples are given.

Title: Improvements in electro-dynamic brakes
IPC: H02K49/04
Filed: 1951-10-16
Abstract: 698,442. Eddy-current brakes. ELECTROMECANIQUE DE L'AVEYRON. Oct. 16, 1951 [Nov. 14, 1950; Aug. 2, 1951], No. 24112/51. Class 35. In, an eddy-current brake of the rotary magnetic disc type having poles 3 placed laterally on each side of the disc 1, the distance between the pole-supporting plates 4, 4a varies in accordance with thermal variations in the length of the machine shaft 2 so that the working air-gaps a, b on either side of the disc are kept equal to preserve magnetic balance. In its simplest form, Fig. 1, the pole support 4a is pushed outwardly against the pressure of spring discs 10 on guides 8 by pressure due to the shaft expansion transmitted through the bearings 5, so that the air-gaps a, b both expand equally. In a modification, the pole-supporting plates are made flexible to produce the same effect. In a further modification, the guide-rods 8 have shoulders limiting the inward motion of the plates 4, 4a due to the poles when energized, and also carry springs urging them apart to separate the poles in the de-energized condition, the bearings having sufficient axial play to allow this motion. Thermal expansion of the shaft pushes the plates apart against the magnetic attraction and produces equal increases of airgap as before. In a further modification, Fig. 2, springs 11 are interposed between the bearings 5 and the corresponding plates 4 and 4a which have housings 13 in which the bearings are slidable. When the brake is out of action, the springs 11 force the slidable plate 4a against the action of the weaker springs 10a up against stops 15, thus expanding the air-gaps. When the poles are energized, the springs 11 are compressed, thus releasing springs 10a by movement of the bearings 5 in their housings up against shoulders 14 which determine the minimum working air-gaps, expansion of the shaft causing movement of the plate 4a to widen the air-gaps as before. In a modification of Fig. 2 designed to ensure that the movable plate 4a remains parallel to the end-cover 16, the sliding studs 9 are replaced by a series of ball-ended links joining the plate 4a to the end-cover. The pole spacing in the energized condition is still determined by the length of the shaft but the plate 4a turns about its axis to vary the angle of the links and so allow it to move axially without tilting.

Title: New dyestuffs of the anthraquinone series and process for making them
IPC: C09B62/024
Filed: 1954-08-19
Abstract: The invention comprises anthraquinone dyes of the formula: R-X-B, in which R is an anthraquinone dyestuff residue, X is a nitrogen bridge, and B is the residue of a heterocyclic compound having no dyestuff character, which contains a single exchangeable halogen atom bound directly to the hetercyclic nucleus and contains no aromatically-bound free amino or hydroxy groups, and in which one of the residues B and R, advantageously R, contains a sulphonic acid group, and in particular dyes of the formula: <FORM:0784221/IV (b)/1> in which R represents an anthraquinone residue bound in a -position to the NH-group, R1 represents a monocyclic arylene residue, X is O, S, or a nitrogen bridge, and A is an organic residue free from aromatically bound hydroxyl and amino groups and having no dyestuff character, and in which one of the residues R, R1, and A contain a sulphonic acid group.  They are made by condensing an anthraquinone dyestuff containing at least one amino group with a reactive hydrogen atom with a heterocyclic compound having at least two exchangeable halogen atoms bound directly to the heterocyclic nucleus and having no free aromatically bound hydroxy or amino groups and no dyestuff character, so that one of the halogen atoms remains in the product. Alternatively, a cyanuric trihalide may be condensed with the anthraquinone to replace one halogen, and the primary product reacted with a hydroxy, mercapto, or amino compound having no dyestuff character free from further aromatically bound hydroxy or amino groups to exchange a second halogen.  The products dye or print silk, leather, nylon, and superpolyurethanes.  In examples: (1) the primary condensation product from cyanuric chloride and aniline is condensed with 1-amino-4-(41-aminophenylamino) - anthraquinone - 2,31 - disulphonic acid, and that from cyanuric chloride and ammonia is condensed with 1-amino-4-(41 - aminophenylamino) - anthraquinone - 2 - sulphonic acid; (2) 2,4-dichlorpyrimidine is condensed with 1 - amino - 4 - (41 - aminophenylamino) - anthraquinone - 2 - sulphonic acid or with 1-amino-2-sulpho-4-(41-aminophenylamino) - anthraquinone - 31 - sulphonic acid diethylamide; (3) 2,4-dichloroquinazoline is condensed with 1-amino-4-(41-aminophenylamino) - anthraquinone - 2 - sulphonic acid.  A dyeing example is given using wool.  Other heterocyclic bodies specified are 2,4-dichlorquinoline, N - methyl - 2,4 - dichlorpyrimidine, 1,4-dichlorphthalayine, and the primary condensation products of cyanuric halides with various specified alcohols, phenols, mercaptans, thiophenol, alkylamines, arylamines, cyclohexylamine, amides, urea, thiourea, sulphonamides, carbamic and aminoacid esters, and sulphones.
